Specification of Letters Patent.

Patented Sept.l 26, 1916.

Application filed April 7, 1916. eiia1Nof u89,657',

To all whom it 4may concern Be it known that I, ROBERT H. HAssLER,

a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specication.

The object of this invention is to provide a radius rod and connections between the axles and frames of vehicles, through which the stresses and shocks from the axles will be yieldingly resisted. ,The device of this invention is a modification of those shown inh my Patents No. 1,165,405 and No. 1,164,618.

This\,invention may be applied yto the steering or to the driving axles of vehicles, and comprises a triangular truss formed by the axle and two radius rods. One end of each radius rod is rigidly secured to the axle at points widely separated. The other two ends' of the radius rods converge toward each other,\ and are joined together by a short stud. rIhis stud is rigidly secured to one coil` of the volute -spring,-other coils of the. same pring being held to the frame members of tne car.

In Patent No. 1,165,405, above referred to, the radius rods and volute springs are arranged in such a way that the stresses are delivered almost entirely in a direction radial of the springs, and in Patent No. 1,164,618, the radius rods and volute springs are arranged in such a way that the stresses are nearly all in a. direction at right angles to the plane of the springs.

The object of the present invention is to more eliiciently use the volute spring than is possible in either of the other two forms, and to subject the spring to strains in both axialand radial directions.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a top plan view of a motorvehicle running gear embodying my invention. Fig. 2 is a longitudinal vertical section of the front end of same on an enlarged scale. Fig. 3, is a cross section of the front 50 axle and the stud connecting the converging ends of the two radius rods, on the line 3 3 of Fig. 4, and Fig. 4 is a section on the line 4-4vof Fig. 3.

Like characters of reference indicate vlike 55 parts throughout the lseveral views of the drawings.

The'inventionmay be applied to either front or rear axle or to both, and Ihave shown it as applied to a front axle of a motor vehicle in which 5 is the frame proper, 6 the frontaxle, 7 therear axle, 8 the road-wheels, 9 and 9` the motor and fly-y wheel housings respectively,lwhich are rigidly attached totheframe, and whenthe/ frame is Ihereafter referred to will be understood as comprisedtherein, and 10 theA front leaf spring between the axle and the frame.

l1 represents the two diagonal radius rods, which have one of their ends screwthreaded and extended through the front axle and there secured by a nut 12 These two rods form la V shaped brace, the two converging ends of which are connectedby a stud 13, which passes through the inner coil `of a volute spring 14 with which it makes a reasonably close t. Wash ers 15 are between the spring and the adjacent ends of the brace-rods 11, whereby bothrods are bolted to the central coil of the spring by tightening up nuts 16 on the threaded ends of the stud. l

The spring 14 is supported by an annular casing 17, having perforated outside lugs 18, for the passage of rivets (or bolts) 19, which secure annular plates 20, to each side oi the casing 17, after the assembly of the spring in the latter. Flanges 21 and 22, integral with the casing 17, provide means for bolting the casing 17 rigidly to the motor and iiywheel housing portions of the main frame.

When one of -the wheels of the car strikes a road obstruction, the triangular truss has three dilerent actions on the volute spring. First, it acts in a radial direction pressing the convolutions toward one another with gradual accumulative eiiect. Second, it acts in an axial direction tending to telescope the convolutions of the spring through one another. Third, it subjects the spring to a torsional strain by which its inner coil is thrown on an angle with its outer coil, this action being emphasized when one of the wheels of the c ar is lifted with reference to the other three wheels. A

lVith the above actions, more movement is afforded the axle-ends than would be possible by any form of universal joint at the converging ends of the radius rods,--and the road wheels are cushioned against shocks in a manner not possible with other known radius rod constructions. At the same time, these results are secured Without the use of any bearing parts, frictional or sliding parts, to Wear loose and rattle,`sucl1 as must be used on any form of universal joint.

Having thus fully described my invern tion, what I claim as new and Wish to secure by Letters Pate-nt of the United States, is-

l. The combination, With a vehicle frame and an axle, of a pair of radius 'rods rigidly secured to the axle, a volute spring, and means for securing' the ends of the radius rods remote from the axle to -a coilof the spring.

2. The combination With a vehicle frame and an axle by which the frame is supported, of'a volute spring and two radius rods rigidly secured at one, end to the axle andjextending to form a V-shaped brace, the converging ends of the radius rods being attached to one coil of the 'volute spring and another coil of the volute spring being fastened to a rigid support from the frame members of the vehicle.

3. The combination of a Vehicle frame, an

axle by ,which the frame is supported, a'

volute spring, a spring support attached to the frame, to which support the outer coil of the spring is fastened, a pair of radius rods rigidly secured at one end to the axle and extending to lform a V-shaped brace, a stud passing through the inner coil of they spring to which the ends of the radius rods remote from the axle are fastened.

The combination of a vehicle frame, :zu axle by which' the frame is supported, a

cylindricai spring-housing having annularl heads, a volute spring assembled in said housing to which housing the outer coil of the spring is fastened, a pair of radius rods rigidly secured at one end to the axle and extending to form a V-shaped brace, and a stud passing through the inner coil of the spring to which the ends of the radius rods remote from the axle are fastened.

In witness whereof, Il have hereunto set my hand and seal at Indianapolis, Indiana, this ist day of April, A. D. one thousand nine hundred and sixteen.
